I fully expect a steady rise as we close in on the launch. If the community is successful first time, it will continue for a bit, then as always, traders will take some profit.
I think the dip will not be as harsh or as deep as normal due to the number of airdrops happening on or just after the mainnet launch. Either way, EOS is the best long-term hold we have ever seen. The RAM trading market, the token renting dApp Chintai and the mentioned airdrops are more than a game changer, they are second income generators :-)
